General Market Information:

Polymerization inhibitors and UV absorbers are important chemicals used in the production of unsaturated polyester resin (UPR), a versatile material widely used in various applications, including composites, coatings, and adhesives.

Polymerization inhibitors are added to the starting monomers to prevent premature polymerization, which can occur during storage or transportation. Common polymerization inhibitors used in UPR include hydroquinone, t-butyl catechol, and benzoquinone.

UV absorbers are added to UPR formulations to protect the resin from the harmful effects of UV radiation, which can cause the resin to degrade, discolor, or become brittle over time. UV absorbers work by absorbing the UV radiation and converting it into heat, thereby preventing it from reaching the resin. Common UV absorbers used in UPR include benzotriazoles.

The use of polymerization inhibitors and UV absorbers in UPR formulations helps to ensure the resin remains stable and usable over extended periods of time, as well as maintaining its desired physical and mechanical properties.
